Sinotech Tv Ordeal

Bought a Sinotech Tv in May 2021, early Sep 2021 the tv went black (you could hear voices but cant see pictures), took it back to the shop 14 Sep 2021 because i know i still have the 6 months warranty. Upon arriving at the shop i was told the person(his name is Cannan) who normally books in tv maybe for repairs is not in and that i must come back the next day, told theme i cant come back just to stand and hear them telling that the tv needs repairs but one lady took copy of the receipts to confirm i bought the tv there and that its has the warranty and my phone numbers to call me, to date no one called from the shop, instead i'll call, some will put the phone down and not bother to call and give answers of where the tv is and the progress. On the 23th Sep 2021 called the shop AGAIN, ended up speaking to Neil (Manager/Supervisor)whom too took my details and promise to come back to me - he never did. Today 06 Oct 2021 called the shop ONCE MORE, spoke to a lady called Thembi but she ended up putting my phone down, i redialed and speaks to Neil gave him the same details as last time, WORSE thing is he lets me hold for 6mins. Now is this shop really gonna fix my tv or they are waiting for the warranty to expire because what they are doing is pathetic and unprofessional
